VALVE FOB- WATER DISTRIBU'I'IbN.

Specification of mm. Patent.

Patented Mar. 26, 1912.

Application filed June 14, 1911. Serial No. 688,148.

To all whom it may concern Be it known that I, THOMAS GRA NT Cooxn, acitizen of the United States, reslding at Chicago, in the county of Cookand State of Illinois, have invented new and useful Improvements inValves for Water Distribution, of which the following is aspecification.

This invention relates to improvements in valves for water distributionand more particularly to compound faucets.

It is the object of this invention to construct a compound faucet,commonly termed a combination bib, where cold water, hot water, or anydesired mixture of the two flows from a single discharge with the partsso arranged that a single valve controls both the cold and hot water,and a'mixture of the two of a desired temperature may be accuratelyproduced.

I It is a further object of this invention to construct a combinationbib in which leakage is prevented without the use of packing nuts,stuffing-boxes, packing or stuilin of any kind and in which all thewearo the vmovable parts that would tend to produce leakage is automaticallytakenu While thepreferred forin of t invention is illustrated on theaccompanying sheet of drawing yet it is to be un erstoo that minordetail changes may be made without departing from the scope thereof.

Figure 1 is a view in front elevation with partsin section illustratingthis invention. Fig. 2 is a view in full side elevation. Fig. 3 is aview in horizontal section of the rotatable valve member taken on theline 1 -2 on Fig. 1. 4

The pipes 1 and 2 leading from the hot and cold water mains are broughttogether in front and enter on diametrically o posite sides'of, a valvechamber 3 in the orm of a truncated cone. corresponding shape but oflesser depth is mounted. to rotate in the chamber 3. Throu h a centralopeningin the top B of thevaIve chamber 3 a valve stem D passes and issecured to the top A of the conical valve 4. A sleeve 5 integral withthe valve chamber 3 extends upward from the top surroundin the valvestem D, and of sufiicient inside diameter to allow for a coil spring Fabout the valve stem D. The spring rests upon the top B of the valvechamber 3 and is held under compression by a washer 6 at the topsurrounding the valve stem D A hollow'valve 4 of and secured thereto bya pin 7. A cap E is placed about the valve stem and secured to the topof the sleeve for protecting the spring and keeping foreign matter fromentering the sleeve. The usual hand wheel Y O is secured to the outerextremity of the valve stem.

As above stated the valve 4 is hollow and in the form of a truncatedcone. The water from the hot and cold mains enters through ports 8 inthe side of the valve. A central discharge port 9 is formed in thebottom of the valve which is provided with a depending flange or sleeve10 screw threaded at the bottom to receive a securin nut H for arotatable discharge nipple The pipes 1 and 2 leadin to the hot and coldwater mains are provided with flan es G and the extremities are screwthrea ed and provided with locking nuts K for securing the fixture inplace. I

As shown in Fi 3 the conical valve 4 is provided with a p urality ofports 8 which are so arranged. that when the valve 4 is in the positionshown in Fi 1 and 3 none of the ports register with either pipe. Theports are so disposed and are in such relation to each other that bycontinued rotation of the valve 4 the full discharge from one main,three quarters of that main and one quarter of the other, a fulldischarge from both at once, a quarter of the first and a full dischargeof the second, a full discharge of the first and a half discharge of thesecond will be respectively delivered. The conical valve bein retainedagainst the conical valve cham er by the sprlng u on the outer side atthe top of the chem er it is not.

necessary to use packing of any kind to prevent leakage. The constantrotation of the valve will wear the parts eventually and; the springconstantly drawing the valve upward will compensate for such wear. Bythe arrangement of the ports any desired temperature in the dischargemay be preduced' by turning thevalve to the proper position. v

What I claim is:

In a combination bib or faucet, a conicalvalve chamber with sidessloping upward having an open bottom and closed to pi es leading tromopposite sides of the 0 am r to the mains, a hollow rotatable valve comprising corres ondingly shaped walls, a closed top, a c osed bottomrovided with a small central discharge ori cc, and a plurality of portsof varying sizes provided in thereon, a cap surrounding the valve stem10 the valve walls adapted to register with the and forming a closurefor the sleeve, the pipes, a valve stem secured to the topof thedischarge orifice of the valve provided with valve passing through anorifice in the :top a depending flange forming a' securing of thechamber, an Integral sleeve upon the means for a discharge nipple. v
